SNAP-HOOK.

ESPBCIFICATION forming part of Letters Patent N6. 340,830, dated April 27,1886.

Application fi1efl March 1, 1886. Seria1No. 193,608. (i\*o mde1.)

T0 all whom z't may concern:

Be ib known that I, JOHN H. SHAW, 0f New Haven, in the county 0f New Haven and State of Oonnecoicut, have invented anew Improvernenb in Snap-Hooks; and I C hereby declare the following, when taken in counection with aecompanying drawings and the ietters 0f reference marked thereon, 150 be a fu1l; c1ear, and exact description of the same, anti which said drawings constitute part; of bhis specification, and represent, in-

Figure l, a perspecbive view; Fig. 2, a perspecbive view of he body as formed in easting With the side open; Fig. 3, a longitudinal centra1 section showing a side view of the holt and spring; Fig. 4, a transverse secbion forward 01: faire lugs und open; Fig. 5, the Same section closed.

Tl1is invention relzrtes t0 an improvement in snap-hooks, and particularly 110 tl1at dass in which bhe body is of tubular shape, with a p ab one end and a hook ab the other, and

a bolb arranged to slide in said body, the said 100111 rnoved by means of athnmb-piece,which extends outward through a, longitudinal slob in the body 0r harre], and a spring hold said holt against the end of the h0oln In this dass 0f snap-hooks it; is desirable that tahe 81013 in the body should extend through snbstan: tially its who1e length t0 a1low the escape of water and dirt; bnb if the slot in the body extends throngh its entire 1ength the holt: is iiable 110 be pressed so far into the body upon be spring as t0 cause the spring to set.

'lhe object 0f this imention is so preserve the opening, and yet avoid this difficnlty; and it consists in constrneting Ehe sides 0f the body wit-h ears, which, when tzhe sides are bent toward eaeh other t0 embrace the spring and b0lla, Will meet, and fihereby form a bridge or stop, against which the bhnmb-piece on the 100113 Will strike, and thereby prevent; Ehe bolt from biaing pressed so far into the body as to set the spring.

A represents t-he body of the snap, which is preferably east wibh its sides opened in U shape, as shown in Fig. 2, the deph 0f the sides such that when turned inward in the usua1 manner to inclose bhe holt and spring they will leave alongitudinal opening between the two edges.

The body is constructed wit-h a 100p, a, ab one end, and a hook, b, ab the other end, in the usual manner. Preferably on nach edge 0f the body and midway 0f its length a Ing 0r projection, d, is formed, so that when the studs are turned toward each other the said lugs will form a bridge across the opening, as seen in Fig. l. The holt e is provided wit-h a thumhpieee, f, adapted '00 slide longitudinallyin the body, the thumb piece extending npward through the forxvard portion 0f theslot. The spiral spring g is sei; into Ehe body in rear of the hook, and takes a bearing ab one end against bhe 100p end of the body und ab lhe other end against; the holt e. The spring anti holt are -placed in the body, and the sides turned toward each other until the 1ugs dsubstantially meeb. The spring and holt are thereby held in position, and the 1ugs form a bridge 0r Shop, against which the thurnb-piece of the holt will strike before the spring is pressed so close as t0 cause it t0 seb. This interrupbion 0f the continuity of Ehe sl0t does not materially detraob fron1 it; as a means f0r keeping t;he spring clearand free; bnt beczruse 0f its stopping the holt in its opening 1novemen1s it greatly increases the durabilityof the hook.

While I prefer to constrnct the body with a 1ug 0n each side, ib will be understood that; the Ing nmy be arranged 011 0ne side only, as indicated in broken lines, Fig. 2.

I elaim In a snap-hook, the combination of the body A, construeted With a 100p, a, ab one end, anal With a hook, b, ab the other end, the sides of the said body turned toward each other, bat; so as t0 leave aspace between bhen1 longitudi nally, the said space interrupted by a Ing, d, midway ofthelength of thesideswith aspring, g, and holt; e in said body, the holt provided With a thurnbpiece extending out through the s1ob forward 0f bhe said Ing, bhe said thumbpiece and 111g operating t0 arresb 131 1e inward movement of the boit, substantially as deseribed.
